If f(x) = 6 – 5x and g(x) = 4x – 1, evaluate f(x) – g(x) for x = –2. A. –11 B. 7 C. 9 D. 25

Answers

Answer:

D. 25

Step-by-step explanation:

f(x) = 6 – 5x and g(x) = 4x – 1

We want to subtract.

f(x) -g(x)= 6 – 5x -( 4x – 1)

Distribute the minus sign

6 – 5x - 4x + 1

If u is an algebraic expression and c is a real number such that c>0, then the equation |u|>c is equivalent to a. u>-c or u>c. b. u<-c or u>c. c. u<-c or u

Answers

Answer: u<-c or u>c (choice B)

Explanation

Consider the example |x| > 5.

On a number line this will mean either x > 5 or x < -5. We're looking for values of x such that they are more than 5 units away from 0.

A value like x = -7 fits the description (since it's 7 units away from 0). While something like x = 1 isn't a solution.
